CHARLES H. HANSHAW, 0F BELOIT, WISCONSIN, ASSIGNOR OF ONE-HALF TO JOHN NIELSEN, OF BELOIT, WISCONSIN.

Specification of Letters Patent.

Patented May 25, 1915.

Application filed September 21, 1914. Serial No.862,746.

To all whom it may concern Be it known that I, CHARLES H. HAN- SHAW, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Strainer Attachments for Pumps, of which the following is a specification.

My invention relates to an attachment adapted to be secured to the spout or mouth of a pump for holding a strainer-member, such as a section of cloth, in the path of travel of the discharging water to strain the same, such pump being preferably employed to draw soft-water from a cistern or the like, while not necessarily restricted to such use.

An important object of the invention is to provide an attachment of the above mentioned character, which maybe quickly and conveniently secured to pitcher spout and other pumps, and having means for receiving and holding a straining member, in cooperative relation to the spout of the pump.

A further object of the invention is to provide an attachment of the above mentioned character, which is simple in construction, inexpensive to manufacture,strong and durable.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a perspective view of the attachment, applied to a pump, Fig. 2 is a plan view of the same removed, Fig. 3 is a side elevation of the same, and, Fig. 4 is a longitudinal section through the spout and the attachment applied thereto.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a pitcher spout pump of any well known or preferred type, having a discharge spout or mouth 6 provided with a depending a pair of oppositely arranged turns or b di ls 10 and 11, to receive and hold therebetween a strainer-member 12, formed of cloth or other suitable material. When the cloth 12 is forced downwardly to provide a pocket to receive the water, the same puckers or wrinkles, which materially aids'the coils 10 and 11 in holding the cloth. The ends of the coils or turns 10 and 11 are extended as shown at 13, and twisted together, as shown, for providing a relatively rigid shank 14. At the inner end of the shank 14 the portions of the section of wire diverge forming angularly arranged arms 15, having coil springslfi at theouter end thereof. These coil springs are extended to provide L-shaped attaching arms 17, the upper ends of the vertical arms thereof carrying downwardly extending hooks 18, as shown.

In the use of the attachment, thestrainermember l2-is secured to or within the frame 9 by passing the same between the coils 10 and 11, and the attaching arms17 are, placed upon the spout 6, the hooked ends 18 engaging the upper longitudinal edges .of the spout, while the shank 14,.is arranged below and in engagement therewith. The inner portion of the coils 10 and 11 are arranged behind the flange or lip 6' whereby the deviceis held against accidental displacement. In this manner the attachment is securely detachably connected with the spout, and may be removed therefrom in a-convenient and expeditious manner. The coil springs 16 provide a yielding connection between the attaching arms 17 and the arms 15 of the shank 14, whereby the attachment is yieldingly retained upon the spout 6 and is selfadjusting to fit spouts of different sizes.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 2-- 1. An apparatus of the character described, comprising a pair of coils arranged adjacent each other and adapted to receive and hold therebetween a section of foraminous material, a shank attached to the coils, substantially vertical coil springs and havand means connected with the shank to seing lateral extensions at their upper ends cure the same upon a support. o substantially as described.

2. Apparatus of the character described, In testimony whereof I aflix my signature 5 comprising a section of Wire bent upon itself in presence of two witnesses.
